Title: dmraid modules not properly loaded during installation Status in linux package in Ubuntu: New Bug description: There are actually 2 problems with this one. First is that although Ubuntu 22 Desktop does indeed see FakeRAID cards, it does a partition probe before dmraid sets up the array. On a system with a LSI Megaraid (older card, fakeraid) card I created the RAID array in the BIOS of the card then booted the desktop install. Then ran Live. At the Live desktop at the terminal prompt /dev/mapper/ddf1_4c5349202020202020000055000000000004711471100001450 was visible however fdisk -l on that device showed an actual disklabel (msdos partition table) existed along with a partition #1 completely filling the disk. Executing partprobe /dev/mapper/ddf1_4c5349202020202020000055000000000004711471100001450 created the /dev/mapper/ddf1_4c5349202020202020000055000000000004711471100001450 /dev/mapper/ddf1_4c5349202020202020000055000000000004711471100001450p1 entries with the p1 entry lined to /dev/dm-1 So I then ran the installer and at the disk screen changed grub install to /dev/mapper/ddf1_4c5349202020202020000055000000000004711471100001450 instead of /dev/sda and then I installed Ubuntu on the now visible first partition However after the install completed the system attempted to boot and errored out at an initramfs prompt with: ALERT! UUID=68ca7f1a-c462-4f7c-9657-05d3ad04e4ee does not exists. Dropping to a shell! I ran the following command and got this output: dmraid -ay 165.190010] device-mapper: table: 253:0: raid: unknown target type ERROR: device-mapper target type "raid" is not in the kernel: RAID set "ddf1_4c5349202020202020000055000000000004711471100001450" was not activated To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2028471/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
